650mA, Step-Down DC-DC Converter for RF Power Amplifiers

1 General Description

2 Key Features

ꢀ

PWM Switching Frequency: 2MHz

The AS1332 is a step-down DC-DC converter designed

to power radiofrequency (RF) power amplifiers (PAs)

from a single Li-Ion battery. The device also achieves

high-performance in mobile phones and similar RF PA

applications.

Single Lithium-Ion Cell Operation (2.7V to 5.5V)

Dynamic Programmable Output Voltage (1.3V to

3.16V)

ꢀ

Maximum load capability of 650mA

The AS1332 steps down an input voltage of 2.7V to 5.5V

to output voltages ranging from 1.3V to 3.16V. Using a

V_CONanalog input, the output voltage is set for

High Efficiency (96% Typ at 3.6VIN, 3.16VOUT at

400mA) from internal synchronous rectification

controlling power levels and efficiency of the RF PA.

ꢀ

Current Overload Protection

Thermal Overload Protection

Soft Start

The RF interferences are minimized due to the fixed-

frequency PWM operation. The battery consumption is

reduced to 0.01µA (typ.) during shutdown.

8-pin WL-CSP

Because of the high switching frequencies (2 MHz) tiny

surface-mount components can be used. Additional to

the small size the amount is also small. Only three

external components are required, an inductor and two

ceramic capacitors.

3 Applications

The AS1332 is an ideal solution for cellular phones,

hand-held radios, RF PC cards, and battery powered RF

devices.

The AS1332 is available in a 8-pin WL-CSP.
